[Translated article] Surgical treatment of ipsilateral bifocal tibial fractures: A challenge for the surgeon.

Introduction: The association of ipsilateral tibia fractures has a low incidence, being up to 3.2% of total tibia fractures. Currently there is no gold standard regarding the ideal surgical treatment. The objective of this study is to analyze the surgical treatment and the radiographic and functional results, as well as the associated complication rate of ipsilateral bifocal tibia fractures.

Material And Methods: Retrospective observational study in our hospital from 2010 to 2022 of 24 patients who underwent bifocal fracture of the ipsilateral tibia. Demographic and surgical data and complications during follow-up were included.

Results: The 24 patients were classified into Group 1 when they presented a fracture of the plateau and distal tibia (25%), Group 2 with a fracture of the plateau and diaphysis (33%) and Group 3 with a fracture of the diaphysis and distal tibia (42%). Three patients underwent surgery with 1 implant and 21 patients with 2 implants. The average follow-up time in outpatient clinics was 2 and a half years. At one year, 22 patients (92%) had full weight bearing and 2 patients had partial weight bearing (8%) due to the sequelae of the fractures. The average time for consolidation of the diaphysis was 7.75±2 months, with no significant differences observed between Group 2 and Group 3 (p=0.06). The average time for consolidation of the metaphysis was 3.50±1.5 months, with no significant differences observed between Group 1 and Group 2 (p=0.065). Seven patients (30%) had complications during follow-up.

Conclusions: Bifocal tibia fractures can be treated using a combination of intramedullary nailing and plate osteosynthesis with good long-term results, obtaining an optimal union rate and low complications. In addition, it facilitates the reduction of the fracture, thus facilitating the patient's recovery and obtaining good long-term functional results.
